Going through warranty hell. Main breaker is crap, and alternating pairs of breakers are not getting power (so, 50% of appliances/outlets are out).
I've been fighting for a new panel because the panel is ancient with old Crouse Hinds breakers, but now I'm told my family will need to wait over a week before they can get it special ordered (the main breaker is an old Crouse Hinds MD-A 200A bubble breaker).
Can the MD-A 200A be replaced with a newer Murray MPD2200 safely? Downsides?
Comments/Reviews on Amazon seem to convey that it's no problem, however nobody provided a specific model they were upgrading from, aside from saying "old Crouse Hinds" breakers, and I'm not sure why electricians say to avoid using non-original parts.
I have experience replacing a breaker here and there, and I swapped out wiring within the last few days to sacrifice the disposal for the dishwasher, but I haven't replaced a main breaker before.
